Top Music, Gaming flop!

Did I buy the KH with the option to extend the headset!
My main focus was for me gaming / localization in games!
However, these needs could not fulfill the COP as it is easy to bassy and is inaccurate, despite hours of configurations of the sound card!
However, for KH the music top, rich bass which can be set to make music for a treat!
Also think that the COP more for people who want to listen to music undisturbed in the subway or bus with the mobile phone / MP3 player (perfectly possible thanks to the closed structure)
The comfort is not outstanding but ok!
Sonically, I find the other Beyerdnamic KH better (DT 990PRO, DT770 Pro)
